Title: Manufacture of thin-walled cylinder
Inventor: MIKI SUMIO
IPC: B21D22/16
Filed: 1981-05-19
Abstract: PURPOSE:To obtain a thin-walled cylinder having simple, uniform distribution of thickness deviation and reduce man-hours for balance correction by grinding a spinning worked cylinder formed by blanking work or making the mandrel eccentric by blanking. CONSTITUTION:The surface of a spinning worked cylinder 1 formed by blanking is ground along its axis. After forming a ground part 1a, end plates 2 are attached on both sides, and a thin-walled cylinder is manufactured. Since the cylinder thus obtained has a ground part 1a which is ground uniformly, it has uniform distribution of thickness deviation. Accordingly, when this is rotated at  high speed, it shows very simple mode of vibration. Therefore, balance correction can be made very easily. Or, a mandrel 3 is fitted to a rotating shaft 4 eccentrically by blanking, and a work 5 is placed at the tip. A forming roller 6 is moved along the axis at a desired lancing rate while rotating the shaft 4.  Thus, a cylinder having simple, uniform distribution of thickness deviation is obtained.

Title: Controlling device for tension of belt
Inventor: NARA AKIO
IPC: B60K25/02
Filed: 1980-06-03
Abstract: PURPOSE: To improve a transmitting efficiency of power to a belt, by giving the press load to the belt which transmits power to an auxiliary unit from an engine, by a spring in case of weak tension and by an idler pulley in case of trying to give the stronger tension.  
     CONSTITUTION: The fixed rotary moment is given to a lever 16 centering a supporting shaft 20 by a torsion spring in the casing 31, at the time of regular operation of an engine. the fixed, minimum tension is given to a belt 2, because the lever 16 is pivotally rotated in the counter-clockwise direction and an idler pulley 11 pushes the belt 2. On the other hand, when the load to an auxiliary unit is increased, a control valve 60 is changed over to conduct the negative pressure to a diaphragm chamber 50 through an intake pipe of the engine. By this operation, the diaphragm 51 is brought into operation to pivotally rotate the lever 16 in the counter-clockwide direction centering the shaft 20, so that the pressing force against the belt 2 is further increased and strong tension is given to the belt 2.

Abstract: PURPOSE: To prepare a high quality acetic acid, in high yield, suppressing the by- production of carbon dioxide and formic acid, by oxidizing acetaldehyde with molecular oxygen in the presence of a catalyst comprising manganese acetate and cerium acetate or further copper acetate at specific ratios.  
     CONSTITUTION: Acetic acid is prepared by oxidizing acetaldehyde with oxygen or an oxygen-containing gas in the presence of a catalyst which comprises manganese acetate and cerium acetate or manganese acetate, cerium acetate and copper acetate. The weight ratio of the manganese acetate and cerium acetate (as metals) is 10:1W 3:1, pref. 6:1W4:1 and that of the manganese acetate, cerium acetate and copper acetate is 10:1:0.1W3:1:0.3, pref. 10:1:0.25W3:1:0.2. The use of the catalyst reduces the by-production of carbon dioxide remarkably, improves the yield of acetic acid, and suppresses the by-production of formic acid and formalin which has undesirable effects to the purification cost and the quality control.

Title: Optical method and apparatus for measuring displacement
Inventor: MORI SADAO
IPC: G01B9/02
Filed: 1987-03-31
Abstract: PURPOSE:To make it possible to eliminate an erroneous value due to the disturbance of an optical fiber and to take out and measure only the displacement of an object of measurement, by using two beams of light whose planes of vibration are vertical to each other so as to measure the amount of displacement of the object and by taking the average of the measured values. CONSTITUTION:Two beams B1 and B2 of light having different planes from each other, which are emitted from a light source 1, are applied to an object 9 of measurement and a reference plane 8 through an optical fiber 5. Reflected beams B1T', B2T', B1T'' and B2T'' therefrom are led onto the measuring element side through the optical fiber 5 again. On the occasion, phase errors of the reflected beams B1T', B2T', B1T'' and B2T'' passing through the fiber 5 are varied due to such disturbances as a change in an ambient temperature, a change in the atmospheric pressure, vibrations given to the fiber 5, etc. applied to the fiber 5, and this causes an error in measurement. Therefore, two beams B1 and B2 of light whose planes of vibration are vertical to each other are used, the amount of displacement of the object 9 of measurement are measured by means of Doppler displacement meters 15 and 16, and the mean value of the measured amounts is taken. By this method, the erroneous value due to the disturbances of the fiber 5 is eliminated, and only the displacement value of the object 9 of measurement is extracted.

Abstract: PURPOSE:To prevent the reduction in speaker sound volume of a speaker slave equipment due to a wire resistance between a master equipment and the slave speaker by providing a constant current amplifier driving the slave speaker equipment and an operational amplifier applying arithmetic processing to a voltage generated in a calling line and a constant current amplifier extracting a reception signal on the master equipment. CONSTITUTION:A transmission signal inputted from a transmitter of the master equipment 1 is subjected to power amplification by a constant current amplifier 23 and sent to a calling line by a constant current. Thus, a voltage in response to the impedance of the calling line 3 and the speaker 21 in the case of viewing from an output terminal of a constant current amplifier 13 and a transmission signal is outputted at the output terminal. That is, even if the impedance of the calling line 3 is increased, since the output voltage of the constant current amplifier 13 is increased to compensate said increase, the current flowing to the speaker 21 is unchanged and the speaker 21 is driven by a constant power. Thus, the sound volume of the speaker is not effected by a wire resistance and the wiring for a long range is attained.

Filed: 1988-03-31
Abstract: PURPOSE:To restrain contact surface pressure between a piston ring and a cylinder by communicating a stepped circular groove, a low pressure side space formed at a stepped portion of a stepped piston ring and an intermediate space with one another. CONSTITUTION:A circular groove 3 provided on a piston 2 has a stepped portion, and a piston ring 4 having the similar stepped portion is fitted thereto. High pressure gas above the piston ring 4 is applied to a high pressure side space 5, whereby the piston ring 4 is pressed to a cylinder wall 1 to accomplish sealing. Further, high pressure gas is leaked from the high pressure side space 5 through a contating surface 10 to an intermediate space 9 and applied to a piston ring surface 11 to increase pressing force to the cylinder wall 1. There is provided a groove 101 between the intermediate space 9 and a low pressure side space 7. By this arrangement, high pressure gas in the intermediate space 9 is let go out into the low pressure side space 7 to decrease the pressing force to the piston ring 4 in the intermediate space 9. Accordingly, contact surface pressure between the piston ring 4 and the cylinder 1 can be restrained so as to lessen abrasion.
